Description

[0001] This application claims priority to Chinese Patent Application No. 202411790493.3, filed on December 6, 2024, entitled "An Air Conditioner", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of household appliance technology, and more particularly to an air conditioner. Background Technology

[0003] Traditional residential wall-mounted air conditioners consist of an indoor unit and an outdoor unit. Because the indoor unit contains core components such as a heat exchanger, motor, and fan blades, its size cannot be designed to be compact and elegant, making it difficult to integrate well with home décor. Some commercial kitchen air conditioners use ductwork to supply air to the kitchen, but due to the large size of these ducts and the lack of return air, they are unsuitable for home settings and cannot be integrated with furniture. Furthermore, regardless of whether it's a residential wall-mounted air conditioner or a commercial kitchen air conditioner, the ductwork is fixed at a fixed height, forcing both hot and cold air to diffuse into the room from that height, resulting in slow diffusion and a slower change in indoor temperature. Utility Model Content

[0053] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0054] Traditional residential wall-mounted air conditioners consist of an indoor unit and an outdoor unit. Because the indoor unit contains core components such as a heat exchanger, motor, and fan blades, its size cannot be designed to be compact and elegant, making it difficult to integrate well with home décor. Some commercial kitchen air conditioners use ductwork to supply air to the kitchen, but due to the large size of these ducts and the lack of return air, they are unsuitable for home settings and cannot be integrated with furniture. Furthermore, regardless of whether it's a residential wall-mounted air conditioner or a commercial kitchen air conditioner, the ductwork is fixed at a fixed height, forcing both hot and cold air to diffuse into the room from that height, resulting in slow diffusion and a slower change in indoor temperature.

[0055] In view of this, this application provides an air conditioner in which the air outlet duct is vertically arranged at the target object in the target space, and the air outlet surface of the air outlet duct forms a continuous surface with at least one side wall surface of the target object. On the one hand, this achieves the separation of the air outlet and the traditional indoor unit body, making it convenient to integrate the indoor and outdoor units on the outside of the target space, saving space occupied within the target space. On the other hand, the narrower air outlet duct can be used as a decorative element in home decoration, improving the integration effect of the air outlet duct with home decoration and enhancing the aesthetics of the interior decoration. Furthermore, different air outlet areas of the air outlet duct can be selected according to the diffusion characteristics of hot and cold air, which helps the air discharged from the air outlet duct to exchange heat with the air in the target space with high efficiency, thereby efficiently and quickly adjusting the temperature of the target space.

[0056] The following is for reference. Figures 1-8 An air conditioner according to an embodiment of this application is described.

[0057] Combination Figure 1 and Figure 2 The air conditioner 1000 in this embodiment can be a household air conditioner or a commercial air conditioner. The air conditioner 1000 in this embodiment can include a body 200, an air outlet duct 100, and an air supply duct 300.

[0058] Among them, reference Figure 6 and Figure 7 The body 200 is the component of the air conditioner 1000 that realizes airflow heat exchange and temperature regulation. The body 200 may include a housing 210 and components such as a heat exchanger (including an evaporator 220 and a condenser 230), a compressor 240, and a first fan 250 disposed in the housing 210.

[0059] Combination Figures 1-3 The air outlet duct 100 has an air inlet 102 and an air outlet 1031. The air outlet duct 100 includes an air outlet surface 103, on which the air outlet 1031 is formed. When the air outlet duct 100 is vertically installed at the target object 500 in the target space 400, the air outlet surface 103 forms a continuous surface with the side wall surface of the target object 500 located on at least one side of the air outlet 1031.

[0060] Specifically, the air outlet surface 103 of the air outlet duct 100 can form a continuous surface with the side wall surface of the target object 500 located on one side of the air outlet 1031. Alternatively, the air outlet surface 103 of the air outlet duct 100 can form a continuous surface with the side wall surfaces of the target object 500 located on both sides of the air outlet 1031. For example, the air outlet surface 103 can be seamlessly connected visually and physically with the side wall surface of the target object 500 (such as a wall, ceiling, furniture, etc.), forming a smooth, integrated surface. This design improves aesthetics and optimizes airflow distribution by hiding or integrating the edges of the air outlet surface 103, aligning it with the surrounding structure.

[0061] In the specific implementation process, the target space 400 can be an indoor space, and the target object 500 can be a room or cabinet, etc. The air outlet duct can be installed at the corner 501 of the room or cabinet. At this time, the side wall surface of the target object 500 can be the vertical wall surface of the room or the vertical panel surface of the cabinet. The air outlet surface 103 of the air outlet duct 100 can be connected to the two surfaces of the corner 501, and the air outlet surface 103 can be used as the decorative surface of the corner 501, so that the air outlet 1031 can not be obtrusive to the wall surface or cabinet surface, and the air outlet duct 100 can be integrated with the wall or cabinet, thereby improving the aesthetics.

[0062] Along the height direction of the air outlet duct 100, the air outlet 1031 includes a first air outlet area 1032 and a second air outlet area 1033. The first air outlet area 1032 is located above the air inlet 102, and the second air outlet area 1033 is located below the air inlet 102. The airflow entering the air outlet duct 100 from the air inlet 102 can enter the target space 400 either from the first air outlet area 1032 or from the second air outlet area 1033.

[0063] Combination Figure 3 and Figure 8 Since this embodiment uses the entire air outlet surface 103 of the air outlet duct 100 as the decorative surface of the target object 500 within the target space 400, the air outlet duct 100 can be adjusted according to the height of the target space 400. Thus, the first air outlet area 1032 and the second air outlet area 1033 also correspond to different height spaces within the target space 400. For example, the first air outlet area 1032 corresponds to the upper space of the target space 400, and the second air outlet area 1033 corresponds to the lower space of the target space 400.

[0064] The air supply duct 300 may include an air inlet duct 310 and a return air duct 320. One end of the air inlet duct 310 is connected to the body 200, and the other end is connected to the air inlet 102. The gas in the target space 400 enters the body 200 through the return air duct 320, and the airflow after heat exchange through the body 200 can enter the air outlet duct 100 through the air inlet duct 310, so as to adjust the temperature of the target space 400 during the air circulation process.

[0065] It should be noted that, considering the characteristics of hot air rising and cold air sinking, in this embodiment, when the air conditioner 1000 is used to generate cold air, the air inlet 102 is connected to the first air outlet area 1032, and when the air conditioner 1000 is used to generate hot air, the air inlet 102 is connected to the second air outlet area 1033. That is to say, cold air can be discharged from the upper area of ​​the air outlet duct 100 and diffuse from the upper space of the target space 400 to the surrounding and lower spaces, and hot air can be discharged from the lower area of ​​the air outlet duct 100 and diffuse from the lower space of the target space 400 to the surrounding and upper spaces. In this way, the air outlet area 1034 can be selected according to the diffusion characteristics of hot and cold air, which helps the air discharged from the air outlet duct 100 to exchange heat with the air in the target space 400 with high efficiency, thereby efficiently and quickly adjusting the temperature of the target space 400.

[0066] According to the embodiment of this application, the air conditioner 1000 has an air outlet duct 100 vertically arranged at the target object 500 in the target space 400, and the air outlet surface 103 of the air outlet duct 100 forms a continuous surface with at least one side of the side wall surface of the target object 500. On the one hand, this achieves the separation of the air outlet 1031 and the traditional indoor unit body 200, making it easier to integrate the indoor and outdoor units on the outside of the target space 400, saving space occupied within the target space 400. On the other hand, the narrower air outlet duct 100 can be used as a decorative element, improving the integration effect of the air outlet duct 100 with home decoration and enhancing the aesthetics of the interior decoration. Furthermore, different air outlet areas 1034 of the air outlet duct 100 can be selected for air outlet according to the diffusion characteristics of hot and cold air, which helps the air discharged from the air outlet duct 100 to exchange heat with the air in the target space 400 with high efficiency, thereby efficiently and quickly adjusting the temperature of the target space 400.

[0067] In some embodiments, reference Figure 8 The air outlet duct 100 also includes a surrounding surface located around the air outlet surface 103. The surrounding surface and the air outlet surface 103 together form a complete ring. For example, there can be two surrounding surfaces, in which case the cross-section of the air outlet duct 100 is triangular; or, there can be three surrounding surfaces, in which case the cross-section of the air outlet duct 100 is quadrilateral. The surrounding surface is used to fit against the side wall surface of the target object 500. The air inlet 102 is opened on the surrounding surface, that is, the air inlet 102 and the air outlet 1031 are located on different sides of the air outlet duct 100. This helps to reduce the number of bends 501 in the airflow path, reduce wind resistance, and thus reduce wind power loss.

[0068] In some embodiments, combined with Figure 1 and Figure 3The air inlet 102 is located in the middle region along the height direction of the air outlet 1031. It should be noted that the middle region here is not the exact center of the air outlet 1031 along the height direction, but includes the center of the air outlet 1031 along the height direction and the area within a certain distance from the center. This allows for flexible adjustment of the position of the air inlet 102 according to the demand for hot and cold air. Furthermore, only one air inlet 102 is needed to supply air to both the first air outlet area 1032 and the second air outlet area 1033, which simplifies the ductwork structure of the air outlet duct 100 and the air supply duct 300.

[0069] Optionally, the dimensions of the first air outlet zone 1032 and the second air outlet zone 1033 along the height direction may be the same or different; the air outlet surface area of ​​the first air outlet zone 1032 and the second air outlet zone 1033 may be the same or different; and the shapes of the first air outlet zone 1032 and the second air outlet zone 1033 may be the same or different.

[0070] In some embodiments, combined with Figures 1-3 The ratio of the height of the air inlet 102 to the height of the air outlet 1031 is 1 / 3 to 2 / 3. This means the air inlet 102 can be divided into three equal parts in the height direction, with the air inlet 102 located between one-third and two-thirds of the height of the air outlet 1031. This allows for flexible adjustment of the air inlet 102's position according to the demand for hot and cold air. Furthermore, only one air inlet 102 is needed to supply air to both the first air outlet area 1032 and the second air outlet area 1033, simplifying the piping structure of the air outlet duct 100 and the air supply duct 300.

[0071] In some embodiments, the air conditioner 1000 may further include a damper movably disposed at the air inlet 102. For example, the damper may be a three-way valve, allowing one of the first air outlet zone 1032 and the second air outlet zone 1033 to connect with the air inlet 102. This enables airflow control of the first air outlet zone 1032 and the second air outlet zone 1033, with a relatively simple implementation principle.

[0072] In some embodiments, the air inlet direction of the air inlet 102 is parallel to the air outlet direction of the air outlet 1031, and both are perpendicular to the extension directions of the first air outlet area 1032 and the second air outlet area 1033, which are the height directions of the air outlet duct 100. This parallelism is not absolute, but approximately parallel; it can be considered parallel within a certain angular difference range. Thus, the airflow enters the air outlet duct 100 from the supply air duct 300 via the air inlet 102, and then exits from the first air outlet area 1032 or the second air outlet area 1033. This flow path is approximately Z-shaped.

[0073] It should be noted that when the inventors of this application conducted an air outlet test on the air outlet duct 100, they found that since the air inlet 102 is located at one end of the first air outlet area 1032 and the second air outlet area 1033 respectively, when the airflow enters the air outlet duct 100 from the air inlet 102 and diffuses and exits along the extension direction of the air outlet duct 100 to the other end of the first air outlet area 1032 and the second air outlet area 1033, the flow path of the airflow is roughly parabolic.

[0074] In some embodiments, reference Figure 5 The air outlet duct 100 may include a duct body 104 and a first air-softening plate 105. The duct body 104 may include at least two duct walls arranged at an angle, with their first ends directly connected. These duct walls constitute the aforementioned enclosure surface. For example, when there are only two duct walls, their first ends are directly connected, and the angle between them can be 90 degrees. In this case, the cross-section of the air outlet duct 100 is a right-angled triangle. When there are three duct walls, including two side duct walls and one intermediate duct wall, the first ends of the two side duct walls are connected through the intermediate duct wall, and the two duct walls are parallel to each other. In this case, the cross-section of the air outlet duct 100 is square.

[0075] The second ends of the two first pipe walls can jointly define an air outlet 1031. A first air deflector 105 is disposed at the middle of the air outlet 1031 along its width direction. The first air deflector 105 divides the air outlet 1031 into two air outlet areas 1034 located on both sides of the first air deflector 105. The air outlet direction of each air outlet area 1034 is parallel to the plane of the pipe wall on the side it is located on. Taking the cross-section of the air outlet duct 100 as a triangular example, when the air outlet duct 100 is arranged at the corner 501 defined by the two vertical walls, the two side plates are respectively attached to the two vertical walls. The air outlet surface 103 is inclined relative to the vertical wall. Without the first wind deflector 105, the airflow blows into the target space 400 in a direction perpendicular to the air outlet surface 103, which may directly affect the human body and cause discomfort. However, by setting the first wind deflector 105, the first wind deflector 105 can block and guide the airflow, allowing it to blow out in a direction parallel to the two vertical walls, avoiding direct blowing on the human body. This makes the airflow felt by the human body more like a natural breeze, which is beneficial to improving human comfort and user experience, and also helps to reduce air outlet noise.

[0076] refer to Figure 5In some embodiments, the first flexible wind plate 105 may include a wind deflector 1051 and two air outlet plates 1052. The wind deflector 1051 is parallel to the air outlet surface 103 and is spaced apart from the second ends of the two pipe walls to form air outlet areas 1034 on both sides of the first flexible wind plate 105. In other words, the first air outlet area 1032 and the second air outlet area 1033 both include two air outlet areas 1034 located on both sides of the first flexible wind plate 105.

[0077] Two air outlet panels 1052 are located on both sides of the baffle 1051 along the width direction of the air outlet 1031, and the air outlet panels 1052 are provided with first soft air holes 1054. In this way, a portion of the airflow can be blown into the target space 400 from the corresponding direction through the first soft air holes 1054 and the air outlet area 1034 in sequence, which can further improve the natural wind effect and reduce the air outlet noise.

[0078] refer to Figure 5 In some embodiments, the air outlet duct 100 may further include: two second air softening plates 106, which are respectively located on both sides of the first air softening plate 105. The first end of the second air softening plate 106 is connected to the air outlet plate 1052, and the second end of the second air softening plate 106 is connected to the second end of the duct wall. In other words, the two second air softening plates 106 are respectively located on the side of the two air outlet plates 1052 away from each other. The second air softening plate 106 is provided with a second air softening hole 1061. In this way, a portion of the airflow can be blown into the target space 400 through the second air softening hole 1061 and the air outlet area 1034 to improve the natural wind effect.

[0079] refer to Figure 5 In some embodiments, the air outlet plate 1052 can be connected to the pipe wall. For example, the end of the air outlet plate 1052 away from the air outlet 1031 is connected to the pipe wall. The air outlet plate 1052 includes a first region located inside the second flexible air plate 106 and a second region located outside the second flexible air plate 106. The first flexible air holes 1054 are all formed in the second region, that is, the first flexible air holes 1054 are located outside the second flexible air plate 106. At this time, the airflow in the air outlet duct 100 can be discharged from the first flexible air holes 1054 in the second region and the second flexible air holes 1061 on the second flexible air plate 106, respectively.

[0080] In this configuration, the first region, together with the pipe wall and the second flexible air plate 106, encloses a first flexible air cavity 1062. The first flexible air cavity 1062 has a triangular cross-section, and there are two such cavities. Two air outlet plates 1052, a baffle plate 1051, and the pipe wall together define an air outlet duct 1058. The air outlet duct 1058 has a pentagonal cross-section, and an air inlet 102 is located on the wall of the air outlet duct 1058. A first air passage opening is provided in the first region, connecting the first flexible air cavity 1062 and the air outlet duct 1058. Thus, a portion of the airflow within the air outlet 1058 is sequentially blown out through the first air passage opening, the first flexible air cavity 1062, the second flexible air hole 1061, and the air outlet region 1034, while another portion of the airflow within the air outlet 1058 is sequentially blown out through the first flexible air hole 1054 and the air outlet region 1034.

[0081] Furthermore, since the opening directions of the first soft air hole 1054 and the second soft air hole 1061 intersect, the airflows blown out from the first soft air hole 1054 and the second soft air hole 1061 can be mixed before being discharged from the air outlet 1031. This helps to further improve the soft air effect and reduce the noise of the air outlet.

[0082] refer to Figure 5 In some embodiments, the first wind-softening plate 105 may further include a partition plate 1055. Specifically, the partition plate 1055 is arranged parallel to and spaced apart from the wind baffle plate 1051. Both ends of the partition plate 1055 are connected to two air outlet plates 1052 respectively. The partition plate 1055 divides the air duct 1058 into a main channel 1056 and a second wind-softening chamber 1057. The air inlet 102 is located on the wall of the air duct 1058 in the main channel 1056. The partition plate 1055 is provided with a third wind-softening hole 10551 connecting the main channel 1056 and the second wind-softening chamber 1057. Thus, part of the airflow in the main channel 1056 is sequentially blown out through the third wind-softening hole 10551, the second wind-softening hole 1061, and the air outlet area 1034, further improving the wind-softening effect and helping to reduce air outlet noise. In addition, the partition plate 1055 can enhance the structural stability of the first wind-softening plate 105.

[0083] In some embodiments, the area of ​​the first soft air hole 1054 and the area of ​​the second soft air hole 1061 are equal, which helps to maintain a balance in the air output efficiency of the first soft air hole 1054 and the second soft air hole 1061, thereby improving the soft air effect.

[0084] In some embodiments, the area of ​​either the first soft air hole 1054 or the second soft air hole 1061 is smaller than the area of ​​the third soft air hole 10551. This avoids the situation where the area of ​​the third soft air hole 10551 is too small, which would result in the air outlet efficiency of the first soft air hole 1054 being too low, and consequently reduce the air outlet efficiency of the air outlet duct 100.

[0085] In some embodiments, the air outlet plate 1052 is perpendicular to the air outlet surface 103. This makes the internal structure of the air outlet duct 100 simpler and easier to manufacture.

[0086] refer to Figure 5 In some embodiments, the air outlet duct 100 may further include an air distribution plate 107. The air distribution plate 107 consists of multiple plates spaced apart along the height direction of the air outlet duct 100. The air distribution plate 107 is located between the first air distribution plate 105 and the duct wall. The air distribution plate 107 is provided with through holes. The shape of the through holes can be circular, elliptical, square, etc. By setting the air distribution plate 107, the gas in the air outlet duct 100 can be blocked, preventing most or almost all of the gas in the air outlet duct 100 from being blown to the end furthest from the air inlet 102 before being blown out from the air outlet 1031, thereby avoiding uneven air outlet.

[0087] As a specific embodiment of this application, the proportion of the cross-section of the through hole of the air distribution plate 107 to the total cross-sectional area of ​​the air distribution plate 107 gradually increases from the position of the air inlet duct 1058 to the position away from the air inlet duct 1058.

[0088] Specifically, since the wind speed is higher near the air inlet duct 1058 and lower far from the air inlet duct 1058, this design ensures that the wind speed of the gas blown out by the air outlet duct 100 is similar near the air inlet duct 1058 and far from the air inlet duct 1058, resulting in good uniformity of the blown gas and improving the user experience.

[0089] Specifically, the cross-sectional area of ​​the through holes in the air distribution plate 107 of this embodiment can be changed by changing the number of through holes or by changing the cross-sectional area of ​​each through hole.

[0090] As a specific embodiment, along the height direction of the air outlet duct 100 and away from the air inlet 102, the arrangement density of the air distribution plate 107 gradually decreases.

[0091] Specifically, in this embodiment, the density of the air distribution plates 107 near the air inlet 102 is set to be large, while the density of the air distribution plates 107 far from the air inlet 102 is set to be small. This makes the airflow near the air inlet duct 1058 and the airflow far from the air inlet duct 1058 have similar speeds, thereby making the uniformity of the gas blown out of the air outlet 1031 good.

[0092] In this embodiment, the density of the air distribution plate 107 set at the air outlet 100 and the cross-sectional area of ​​the through holes at the air distribution plate 107 can be designed according to the situation, so that the uniformity of the gas blown out of the air outlet 1031 at different positions of the air outlet 100 of the air outlet 100 is good.

[0093] More specifically, the aperture size of the through holes at the air distribution plate 107 in this embodiment is adjustable. By changing the total cross-section of the through holes at each air distribution plate 107, the proportion of the total cross-sectional area of ​​the through holes to the cross-section of the air distribution plate 107 can be changed, thereby further improving the uniformity of the air output.

[0094] In another embodiment, the air distribution plate 107 of this embodiment can be set with different areas at different distances from the air inlet duct 1058, so as to further increase the uniformity of the air outlet.

[0095] In some embodiments, the air outlet duct 100 may also be provided with a return air zone 108. The return air zone 108 is located on the air outlet surface 103 and is spaced apart from the air outlet 1031 along the height direction of the air outlet duct 100. The end of the return air duct 320 away from the body 200 is connected to the return air zone 108. In this way, part of the structure of the air outlet duct 100 can be used as the return air zone 108, eliminating the need to set up a separate return air structure, which helps to ensure the aesthetics of the air outlet duct 100 after installation.

[0096] In some embodiments, along the height direction of the air outlet duct 100, the return air zone 108 is located on the side of the first air outlet zone 1032 away from the second air outlet zone 1033, that is, the return air zone 108 can be set at the top of the air outlet duct 100.

[0097] Alternatively, in some other embodiments, the return air zone 108 is located on the side of the second air outlet zone 1033 away from the first air outlet zone 1032, that is, the return air zone 108 can be located at the bottom of the air outlet duct 100.

[0098] Thus, the return air zone 108 can be set in various ways, and its position on the air outlet duct 100 can be flexibly set as needed to meet the return air requirements in different installation environments.

[0099] In some embodiments, reference Figure 6 and Figure 7 The housing 210 may be provided with a first connection port 2101 and a second connection port 2102. The return air duct 320 is connected to the first connection port 2101, and the air inlet duct 310 is connected to the second connection port 2102. In this way, the body 200 can be connected to the return air duct 320 and the air inlet duct 310, thereby forming a complete airflow circulation system. Furthermore, by connecting the return air duct 320 and the air inlet duct 310 to the body 200 respectively, it is convenient to adjust the positions of the first connection port 2101 and the second connection port 2102 according to the positions of the various functional components inside the body 200, thereby maximizing the efficiency of airflow circulation.

[0100] In some embodiments, reference Figure 6 and Figure 7The housing 210 may be provided with a first partition 260, which divides the inner cavity of the housing 210 into a first receiving cavity 211 and a second receiving cavity 212. The first receiving cavity 211 is located above the first partition 260, and the second receiving cavity 212 is located below the first partition 260. The heat exchanger may include an evaporator 220 and a condenser 230. The evaporator 220 and a first fan 250 are located in the first receiving cavity 211, and the condenser 230 is located in the second receiving cavity 212. The first connection port 2101 is opposite to the evaporator 220, and the second connection port 2102 is opposite to the first fan 250. In this way, the airflow entering the housing 210 through the return air duct 320 first exchanges heat with the evaporator 220, and then, driven by the first fan 250, is sent from the inlet air duct 310 to the outlet air duct 100, and finally discharged from the outlet air duct 1031.

[0101] The condenser 230, located in the second receiving cavity 212, exchanges heat with the liquid in the evaporator 220, ensuring that the evaporator 220 reaches a suitable heat exchange temperature. The first partition 260 also prevents gas from passing through the space where the evaporator 220 is located and then through the space where the condenser 230 is located, thus avoiding affecting the heat exchange effect.

[0102] Optionally, refer to Figure 6 and Figure 7 In this embodiment, the first partition 260 is provided with at least one first through hole 271 (not shown in the figure), and the first through hole 271 is located at a position corresponding to the location of the condenser 230. Specifically, since condensate easily forms in the evaporator 220 when exchanging heat with the gas, the condensate will flow down the evaporator 220 and drip below. A drip tray can be provided below the evaporator 220, or the first partition 260 can serve as the drip tray. In this embodiment, the first through hole 271 is provided in the first partition 260, which allows the condensate to drip down along the first through hole 271. The first through hole 271 is located above the condenser 230, so that the condensate directly drips onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0103] In some possible embodiments, the first partition 260 is inclined, and the first partition 260 is inclined toward the side where the condenser 230 is located. By adjusting the inclination angle of the first partition 260, the condensate can flow along the first partition 260 to one side and eventually drip onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0104] In some embodiments, reference Figure 6 and Figure 7The first receiving cavity 211 is also provided with a second partition 270, which divides the first receiving cavity 211 into a first sub-cavity 213 and a second sub-cavity 214. The second partition 270 is provided with a through hole 271 connecting the first sub-cavity 213 and the second sub-cavity 214. The evaporator 220 is disposed in the first sub-cavity 213, the first fan 250 is disposed in the second sub-cavity 214, the return air duct 320 is connected to the first sub-cavity 213 through the first connection port 2101, and the air inlet duct 310 is connected to the second sub-cavity 214 through the second connection port 2102.

[0105] The first receiving cavity 211 is divided into a first sub-cavity 213 and a second sub-cavity 214 by the second partition 270, so that the inlet of the air inlet duct 310 is connected to the second sub-cavity 214, while the outlet of the return air duct 320 is connected to the first sub-cavity 213. This separates the exhaust gas from the return gas, preventing the gas from flowing into the air inlet duct 310 without heat exchange, which would affect the exhaust temperature.

[0106] Furthermore, in this embodiment, a through hole 271 is provided at the second partition 270, and the first fan 250 can be a centrifugal fan. The air inlet 102 of the centrifugal fan is provided at the through hole 271, and the air outlet 1031 of the centrifugal fan can be directly connected to the second connection port 2102, so as to directly blow the gas in the first sub-cavity 213 into the air inlet pipe 310.

[0107] Optionally, a fresh air inlet (not shown in the figure) is provided on the side wall of the first receiving cavity 211 in this embodiment, and a fresh air valve (not shown in the figure) is provided at the fresh air inlet so that when the fresh air valve is opened, the first fan 250 blows part of the gas flowing from the first sub-cavity 213 into the second sub-cavity 214 and part of the fresh air entering from the fresh air inlet into the air intake duct 310.

[0108] Specifically, in this embodiment, a fresh air inlet is provided on the side wall of the first receiving cavity 211. When the centrifugal fan blows the gas from the first sub-cavity 213 into the air inlet duct 310, due to the negative pressure, the outside air will enter the second sub-cavity 214 through the fresh air inlet and then be blown into the air inlet duct 310 by the centrifugal fan.

[0109] Specifically, a fresh air valve is installed at the fresh air inlet. When the temperature difference between indoors and outdoors is small, the fresh air valve can be opened, so that the fresh air and the gas in the first sub-cavity 213 are blown into the air inlet duct 310 and then into the target space 400. When the temperature difference between indoors and outdoors is large, the fresh air valve can be closed, and only the gas in the first sub-cavity 213 is blown into the target space 400.

[0110] Specifically, in this embodiment, the fresh air inlet and fresh air valve can be located on the side wall of the first sub-cavity 213 or on the side wall of the second sub-cavity 214. Preferably, the fresh air inlet and fresh air valve are located on the side wall of the first sub-cavity 213, so that the fresh air can follow the gas flowing in through the return air duct 320, pass through the evaporator 220 for heat exchange, and then be blown into the air inlet duct 310 by the centrifugal fan.

[0111] Optionally, refer to Figure 6 and Figure 7 The second receiving cavity 212 may also include a third partition 280, which divides the second receiving cavity 212 into a third sub-cavity 215 and a fourth sub-cavity 216. The condenser 230 may be located in the third sub-cavity 215, and the compressor 240 may be located in the fourth sub-cavity 216. The third sub-cavity 215 may also include a second motor (not shown in the figure) and a second fan 290. The second motor drives the second fan 290 to rotate to dissipate heat from the condenser 230. As the second motor drives the second fan 290 to rotate, the second fan 290 carries away the heat from the condenser 230, preventing the condenser 230 from overheating.

[0112] As a specific embodiment of this application, the third sub-cavity 215 of this embodiment has an air outlet on at least one side wall, and a grille 218 is provided at the air outlet. The condenser 230 is arranged around the side wall of the third sub-cavity 215, which does not have an air outlet. Specifically, the grille 218 in this embodiment can prevent external dust from entering the second receiving cavity 212, and can also protect the outside world from harming personnel caused by the fan.

[0113] Specifically, the second fan 290 in this embodiment can be an axial flow fan.

[0114] As a specific embodiment of this application, the air intake volume of the perforated air supply duct 300 in this embodiment is 650m³. 3 / h-11000m 3 / h. For example, the intake air volume can be 650 m³ / h. 3 / h, 700m 3 / h, 750m 3 / h、800m 3 / h、900m 3 / h, 1000m 3 / h or 1100m 3 / h etc.

[0115] Specifically, when the fresh air valve in this embodiment is closed, and the air is in complete internal circulation, and the wall-penetrating section 350 of the air inlet duct 310 is limited to a diameter of 160mm, the air intake volume in this embodiment can reach 650m³ / h.3 / h-700m 3 / h. When the fresh air valve in this embodiment is opened, combined with the internal circulation and external fresh air, the air intake volume of the air intake duct 310 in this embodiment can reach 1100m³ / h. 3 / h or even higher. Specifically, the intake air volume is related to the diameter of the 300mm supply duct and the power of the centrifugal fan. Of course, the size of the fresh air inlet will also have a certain impact on the intake air volume.

[0116] In some embodiments, reference Figure 3 and Figure 4 The air outlet duct 100 includes multiple air outlet modules 101, which are sequentially connected along the height of the duct. When installed within the target space 400, an appropriate number of air outlet modules 101 can be selected based on the dimensions of the space. This adapts to different installation environments and modularizes the duct, reducing installation difficulty. When the duct 100 is damaged and needs replacement, only the corresponding air outlet module 101 needs to be replaced, reducing maintenance costs for the user.

[0117] The air inlet 102 can be located on one of the air outlet modules 101, and each air outlet module 101 has a partial structure of an air outlet 1031. This makes the construction of the air outlet duct 100 relatively simple and easy to install.

[0118] In some embodiments, at least one of the air inlet duct 310 and the return air duct 320 includes a wall penetration section 350, a transition section 360, and an air supply section 370 connected in sequence. The transition section 360 includes a first end near the wall penetration section 350 and a second end near the air supply section 370. The structure of the pipe wall of the transition section 360 at the first end is the same as that of the wall penetration section 350, and the structure of the pipe wall of the transition section 360 at the second end is the same as that of the air supply section 370. When different air supply sections 370 or different wall penetration sections 350 are used depending on the situation, only the structure of the transition section 360 needs to be changed; the structure of other parts of the duct does not need to be changed, thereby improving the versatility of the duct and reducing production costs.

[0119] For example, only the air inlet duct 310 may include the wall penetration section 350, transition section 360 and air supply section 370 as described above; or only the return air duct 320 may include the wall penetration section 350, transition section 360 and air supply section 370 as described above; or the air inlet duct 310 and the return air duct 320 may each include the wall penetration section 350, transition section 360 and air supply section 370 as described above.

[0120] As a specific embodiment of this application, the cross-sectional structure of the pipe wall of the through-wall section 350 is different from that of the pipe wall of the air supply section 370, and the cross-sectional structure of the pipe wall of the transition section 360 at the first end is different from that of the pipe wall at the second end.

[0121] For example, considering the ease of creating a through-wall hole in the wall, the cross-section of the through-wall hole is set to be circular. Considering the air outlet efficiency of the unit 200, the air supply section 370 can be set to be square. In this case, the first end of the transition section 360 is circular to facilitate connection with the through-wall section 350, and the second end of the transition section 360 is oriented to facilitate connection with the air supply section 370. Thus, it is possible to achieve...

[0122] Generally, the gas flow rate is related to the cross-sectional area of ​​the air supply duct 300. However, due to external factors, its structure can vary even with the same cross-sectional area. For example, since the wall penetration hole is preferably circular, the wall penetration section 350 of the air supply duct 300 is preferably circular. Furthermore, since the air supply section 370 is located outside the wall, considering aesthetics and ease of installation, a square (including rectangles and squares, with a rectangle being preferred) cross-section of the air supply section 370 is more suitable. Therefore, the transition section 360 needs to transition from circular to square, allowing for smoother airflow. When the dimensions of the wall penetration section 350 or the structure of the air supply section 370 change, only the dimensions or structure of the transition section 360 can be modified, thereby increasing versatility and reducing production costs.

[0123] As a specific embodiment of this application, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 to the power of the air conditioner 1000 is less than or equal to 57.37 cm². 2 / kw, where the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200cm². 2 .

[0124] Specifically, in this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power of the air conditioner 1000 is less than or equal to 57.37 cm². 2 / kw. For example, when the power of the air conditioner 1000 in the wall-penetrating section 350 of this embodiment is 1.5 horsepower or higher, the upper limit of the cross-sectional area of ​​the corresponding wall-penetrating section 350 is 200cm². 2 When the power of the air conditioner 1000 is lower, the cross-sectional area of ​​its wall-penetrating section 350 can be smaller. Furthermore, on the one hand, power has a significant limitation on cross-sectional area; for a given power, the cross-sectional area of ​​the air supply duct 300 is fixed. On the other hand, it is subject to existing laws and regulations, and the cross-sectional area cannot be infinitely large. In this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power is designed to be less than or equal to 57.37 cm².2 / kw, and the cross-sectional area of ​​the 350mm section penetrating the wall is less than or equal to 200cm². 2 It not only meets the requirement of a 350mm through-wall section size, but also further meets the power requirement of an air conditioner of 1000 kW.

[0125] In some embodiments, the unit body 200 is located outside the target space 400, and the air outlet duct 100 is located inside the target space 400. For example, the unit body 200 is located in the outdoor space, while the air outlet duct 100 is installed in the indoor space. On the one hand, this achieves the separation of the air outlet 1031 and the traditional indoor unit body 200, facilitating the integrated arrangement of the indoor and outdoor units on the outside of the target space 400, saving space occupied within the target space 400. On the other hand, the narrower air outlet duct 100 can be used as a decorative element, enhancing its integration with interior design and improving the aesthetics of the interior decoration.
